If the CFC are not stopped, ozone will deplete. The hole will grow more bigger.
CFCs are swirled around the world by the global winds. This can take up to ten years for them to reach the lower stratosphere but when there they are still effective at destroying ozone. CFCs in fact have a lifespan in the atmosphere of between 50 and 75 years.
Chlorofluorocarbon (CFC) is a harmful gas because it destroys the ozone layer. It has largely been phased out now, but it remains in the atmosphere for many years and is very destructive. It takes almost seven years for it to rise and move up to the ozone layer where it releases chlorine. This chlorine destroys ozone and keeps reforming and destroying more. Scientists hope the ozone layer will be restored by 2060.
Freon and similar gases like chlorofluorocarbons and halons have only a small influence on global warming. They are much more important for destroying ozone in the ozone layer. Most of these gases are no longer emitted into the atmosphere, but they have a life span of up to 70 years, so they are still damaging ozone. Scientists hope the ozone layer will have repaired itself by 2060.
The man-made gases of CFCs (chlorofluorocarbons). Chlorines and bromines from these gases stay in the atmosphere for years, destroying ozone molecules. This allows the sun's dangerous ultra violet (UV) radiation to reach earth, causing human cancers and damage to crops.
When have you ever known anything to continue at the same rate? The ozone hole was smaller this year than in 2006. So maybe we have a grip on enough bad things to allow the ozone layer to get thicker farther from the equator.
The ozone layer after 5 years is dependent on us. It depends how we use CFC's.
Ozone layer was depleted. It's size has been coming to normal in recent years.
The ozone hole was not there 2000 years back. No CFC's were there then.
Ozone in the ozone layer appears to be decreasing long term, with significant variations annually, every ~11 years, and even every ~121 years. See link below.
Politicians will survive, much as the cockroach has survived for hundreds of millions of years. Politicians rarely mouth anything about ozone layer depletion, because their constituents with money speak much louder.
The ozone layer has been decreased over the years. It is because of use of CFC's.
No. The holes in the ozone layer formed years before H.A.A.R.P. existed.
